Problems of Building Infrastructure Vehicular Ad Hoc Networks Based on SD-WAN Technologies

Abstract

Modern vehicular ad hoc networks based on 5G technologies use external device management within the software-defined networks (SDN) with slicing network level virtualization. The combination of 5G technology and the OpenFlow protocol presents several challenges related to SD-WAN-based virtualization and slicing management. Mobile ad hoc networks with mobile routers require a special approach to the organization for granular flow control, rate limiting and guaranteed bandwidth. The paper discusses the features of SD-WAN solutions in terms of QoS, describes possible approaches to ensuring the security of SD-WAN in VANETs. The proposed solution is built on the principle of integrating the SDN API controller with the edge points of overlay networks and solves the problem of bandwidth overload of overlay networks with encrypted traffic. Model of mobile VANET endpoints with mesh intensive networking are used for discovering optimal traffic management methods with SDN and SD-WAN.
